A file called .config is created inside the Linux sources root directory.
All the changes you will do using make menuconfig will be saved on this file so,
if you want to create your own default kernel configuration, simple copy the new .config
you obtain file in arch/arm/configs with a custom name like at91-myconfiguration.

Download e generate the device tree file

"The Device Tree is a data structure for describing hardware. Rather than hard
coding every detail of a device into an operating system, many aspect of the hardware
can be described in a data structure that is passed to the operating system at boot
time."

When you compile a Device Tree File (.dts) you will obtain a Device Three
Blob file (.dtb) to save in the first partition of your bootable microSD
card together with Linux Kernel image.
